A few months ago I bought the Continuous Ink System for my Canon ip3600.

I am constantly having to do a cleaning to get the magenta to print. Everything I print is missing magenta until I do the cleaning. And you can't just clean the one, so I am just wasting all my ink. Once it starts, it will keep running for the period, but the next day it's gone again.

I have tried filling the cartridge to the brim (no air), and there is no air in the tube.I have even both the refill plug and vent plug out to allow air into the bottle freely.I have not elevated the bottles as instructions stressed to be level with the printer.

I am very frustrated. This is a first time buy from CIS. Do I have to buy another magenta cartridge since my 30 days are up? (I ran out my original carts before installing this system.
